Attached is a picture of a surface loft with guide curves. Ofcourse the curvy spline and straight spline will have differentparameters, but I am curious as how SW determines the parameters ofthe created surface. Why do the isoparams slant downwardinstead of going straight across? I have tried many differentways, but it always ends up the same. The only thing thatseems to make a difference is to add another profile curve ( theshort direction in this example).
